Hinge



Feb. 27, 1923.

R. F. CARPENTER ET AL HINGE Filed Apr. 27, 1918 into the plate 13. The slots of said lugs are horizontal so as to enable said fianges 14 to be adjusted horizontalbv along the plate 13 toward and from each other. to be [hereby capable of embracing and being secured to door casings of different thickness. Preferably the lugs 15 on each tiange are arranged in non-symmetrical relation to said flange. so that each fiange. including its lugs. is identical with the other flange. and the lugs of the two flangcs are in staggercd relation when applied to the plate 13. as shown iu Fig. 6.

Plate 13 carries a horizontal platform 17 on which is a vertically extending sleeve member or socket 18 to receive the pin 9. Surrounding the upper portion of said sleeve and supported upon said platform is an annular cam member 19. This cam member has a central hub portion 20 which fits the slecve IS and is capable of rotatable adjustment about said sleere and of being secured in any adjusted position thereon by a radially extending set screw 21. Member 19 also has an annularly extending cam portion in the form of a tlange 21'. Referring to Fig. 3 the upper surface 22 of this ram is convex. sloping downwardly in opposite directions from the higher middle portion toward two shoulders or abutments 23 near the rear of said member. At the higher central portion. of said surface is a radially extending shallow seat 24-. The lower surface. 25 of said flange is concare or of opposite slope to the upper surface. Cam surfaces 22 and 25 are complementary or have sulostantialliv corresponding configurations and the corresponding parts of these surfaces. that is. the parts directhv above and below each other. are substantially parallel. all as illnstrated in Figs. :2 and VVhen the cam member is assemblcd on tbi` stationary platform. as shown in Fig. l. with its coucare surface 25 uppermost. then the two portions of said surface slope downwardly toward the front of the hinge. Said surfaces 25 support the' antifriction roller ll. Consequently the door Q always terds to more by grarity to the position shown in Fig. 1 with the roller ll at the bottom of the inclined surface 25. By loosening the sct screw 21 the cam member mayr be rotatablltv adjustcd so as to insurc proper alinement of two doors of a pair when said doors are in their normal closed position as shown.

The cam member-ma)`v also be remorcd from thf` sleere 18 and up ended or rererscd. being rc-applied to the sleere IR in the position shown in Fig. 3. ln this position the dooi` bas two normal positions of rest`` one at either side. in which positions roller ll rests in contact. with one or the other of the shonlders 23. Tf the door is morcd away from either of said positions roller 11 rides upwardl)Y along the cam surface 22 and tends to return by gravity to its original position. The reccss or seat2l enablcs the door to be also held in an intermediate normal position, but slight movement of said door in one direction or the' other away from said seat causes said door to more by grarittx`` to normal position.

that we claim is:-

1. hinge. comprising a stationaiwf nieniber. a co-operating 1110 'able member rotatable around a Vertical axis relativc thereto. and a cam member for causing said morable member to swing to normal position. said *am member being rotatably adjustable around said axis to vary the normal position of the movablc member.

2. A hinge. col'nprising a stationary niembei' carrying a cam. and a co-operating member having turning morement relatire thereto around an axis. said cam being rotatahly adjustablc around said axis.

Il. .'x hinge. comprising a stationary member. a co-operating movable member, and a cam member thcrebetween for causing the morable member to swing to normal position. said cam member having two sets of cam surfaces and being shiftablc to two different positions to bring either of said sets of surfaces into action.

4. hinge. comprising a stationary member. a co-operating morable member having tnrning motion relatire thcreto. and a` cam between said members having upper and lower cam surfaccs and adapted to be rercrscd to bring either of said surfaces into action.

5. hinge. comprising a stationary membcr having a hollow tubular socket. a coopcrating morablc member having a pin entcring said socket and adjustable around the axis thcreof. and a cam for co-operation with said movablc member. said cam surrounding said socket.

6. hinge. comprising a stationary member having a hollow socket. a movable member having a pin cntcring said socket. and a cam surrounding said socket and having upper and lower cam snrfaces and adapted to bo rerersed to bring either of said surfaces uppermost for cooperi'ition with said morablc member.

T. hingc. comprising pivotally connected parts. a cam cngaging member carried by one of said parts. and a rcrersible cam member carried b the other part and proridcd with complcmentary upper and lower cam surfaces of substantially the same coniguration.

R. hinge member for attacbment to a supporting part. said member including a base and two parallel duplicate plate members cxtcnding at right angles to said base member. conuccting means between said basiand plate members allowing adjustment of said plate members toward and away from each other to embrace the supporting part.

9. A hinge, comprising pivotally connected parts, a cam engaging member carried by one of said parts, and a reversible cam member carried by the other part and having upper and lower cam surfaces one of said members being rotatably adjustable about the pivotal axis.

10. A hinge, comprising pivotally connected parts, a cam member carried by one of said parts, and a cam engaging member carried by the other part, one of said members being adjustable With respect to the other.

11. A hinge, comprising pivotally connected parts, a cam member carried by one of said parts, and a cam engaging member carried by the other part, one of said members being adjustable around the axis of said hinge.

12. A hinge, comprising pivotally connected parts, a cam engaging member carried by one of said parts, and a reversible cam member carried by the other part and provided with complementary upper and lower cam surfaces of substantially the same configuration, one of said surfaces being convex and the other concave, the convex surface being provided with seats at its Opposite 'ends and near its center, andthe concave surface with a seat near its center.

In testimony whereof we aflix our signatures.

Certificate of Correction.

It is hereby certified that in Letters Patent No. 1,446,449, granted February 27. 1923, upon the application of Robert F. Carpenter and Thomas F. Anderson, of Cleveland. Ohio1 for 1m imprm'ement in Hinges' an error appear-s in the printed specification requiring correction as fnllows: Page 2, lines 106 and 107, claim 5, strike out the words and adjnstnhle around the axis thereof and insert the same to follow the word socket in line 109; and that the said Letters Patent should he read with this correction thereiu that the same may conform to the record of the case in the Patent Ofliee.
